What are three characteristics of a master-detail relationship?

4

A Master-Detail Relationship has several defining traits:5

Roll-up Summaries:This relationship is the only one that allows the Master record to summarize data (sum, count, min, max) from its Detail records (Option C).

Object Types:The Master can be either a standard object (like Account) or a custom object (Option D).

Ownership and Security: The Detail record inherits its owner from the Master record, and as such, there is no "Owner" field on the Detail record (Option E). Additionally, the detail record's security and sharing settings are inherited from the master, meaning permissions are not independent (negating Option B).

Option A is incorrect because an object can only have a maximum of two master-detail relationships.
